OC Showdown 2015 Formula’s third and final round will appeal to anyone with overclocking ambitions, from enthusiasts to first-time tweakers. To ensure a level playing field for all entrants only traditional air- or water-cooling rigs are allowed, meaning off-the-shelf equipment that can be purchased, installed and operated by anyone — regardless of experience. The chosen cooling apparatus must be attached to a system built with an ASUS-branded motherboard.

This ultimate round is divided into three accessible-but-challenging stages, with contestants required to measure their overclocking successes with Intel Extreme Tuning Utility (XTU), Realbench and HWBOT x265 Benchmark.
